Outdoor Winter Nature in Colorado: Rocky Mountain National Park.

The sky was clear, so drove from Boulder to Rocky Mountain National Park. The roads in the park were open, so I spent another day taking pictures in this great National Park. It is cold, and the river is frozen. I got good use out of my Golden Eagle Pass that year.

Outdoor Winter Nature in Colorado: Lily Lake in Rocky Mountain National Park.

During a winter visit to Lily Lake in Rocky Mountain National Park, I observed these two folks out in the middle of the frozen lake. What do you think that they are doing? To give you a hint, they are not ice fishing, but it does have to do with fish under a frozen lake. Please reply if you think you know what they were doing.

Colorado Autumn Road Trip: Big Horn Ram Huddle.

I spotted several Big Horn Rams along Colorado 14 while driving back to Boulder from Arapaho National Wildlife Refuge. One day later I was on the Big Island of Hawaii attending a workshop run by Thom Hogan.
